Are EVs really better if I have a dirty grid?

Almost always yes over the vehicle's lifetime, but the benefit is smaller. Charge on off-peak / solar hours to improve further.

EV vs Gasoline: Which Actually Emits Less Over a Lifetime?

Manufacturing an EV emits more upfront, but grid electricity is cleaner than gasoline. Here's the crossover point and how it varies by country.

Upfront vs use-phase

Building a 60 kWh EV battery emits ~6 tonnes CO₂e. But an EV driven on the average US grid emits 100–120 g/km vs 220–260 g/km for a comparable gasoline car.

The crossover

In the US, EVs break even with gas cars around 20,000–25,000 km. In coal-heavy grids (India, Poland) it can take 60,000 km. In hydro/wind-heavy grids (Norway, Quebec) it's under 15,000 km.
